'Masters of Sex' Star Caitlin Fitzgerald Guests On 'Project Runway': 5 Looks That Prove She Knows What She's Talking About

Sure celebrity judges on reality competition shows are as old as reality competitions themselves. While it's all well and good to see the undeniably chic Caitlin Fitzgerald grab a seat on Project Runway, what would Caitlin Fitzgerald's Masters of Sex character Libby Masters think about the best and worst of PR?

If you're not caught up, Fitzgerld's guest spot episode is called "The Rainway" with designers creating outfits made to stand up to the elements keeping in mind their models actually have to walk in the rain. OK, more like strut through a rain machine they brought into the studio, but still. (Also what's the over/under on at least one model slipping during the show because her designer put her in ginormous heels or a tight skirt with no kick pleats?)

The real Fitzgerald is quite the fashionista, being the subject of numerous fashion blogs, spotted hanging out at fashion week with models, and even stepping out in duds designed by former Project Runway judge Michael Kors. It's clear she's not afraid of bold style choices (and you've gotta be opened minded since PR can be mixed bag of results) but what would her character Libby think of the same fashion challenges? Given the show's wardrobe is painstakingly curated to period accuracy, and Libby is obsessed with maintaining perfection as far as her role as a housewife is concerned (despite all of the change going on around her), when put to the test, Libby's demure looks would come out on top.

So, while we might be able to armchair guess how the actress portraying her might respond, how might Mrs. Masters herself respond to an over-the-top challenge (you know, one that's not her marriage)?
